Abstract

An exhaust system member is provided on a vehicle-width-direction outer side relative to a vehicle body structure on the side of a floor, while avoiding widening of the vehicle and preserving small overlap collision resistance. Embodiments include an engine disposed forward of a partition wall defining a front edge of a vehicle cabin, an exhaust apparatus, a side sill extending along the vehicle front-rear direction on the side of a floor forming a floor surface of the vehicle cabin, and a hinge pillar extending vertically from the side sill. A frame member extends toward the vehicle front side from the hinge pillar and has a front end, on the rear side of a vehicle wheel, overlapping with a vehicle-width-direction length area of the wheel. The exhaust system member is in an area on the vehicle-width-direction outer side of the frame member and on the front side of the hinge pillar.

First claim

What is claimed is:

1. A side vehicle body structure of a vehicle, comprising:
an internal combustion engine equipped on a front side of a partition wall defining a front edge of a vehicle cabin space;
an exhaust apparatus through which exhaust gas from the internal combustion engine passes;
a vehicle body structure extending along a vehicle front-rear direction on a side of a floor forming a floor surface of the vehicle cabin space;
a pillar extending in a vehicle up-down direction from the vehicle body structure; and
a frame member extending toward a vehicle front side from the pillar and having a front end, on a rear side of a wheel of the vehicle, overlapping with a vehicle-width-direction length area of the wheel;
wherein the exhaust apparatus is located in an area on a vehicle-width-direction outer side of the frame member and on a front side of the pillar.

2. The side vehicle body structure of a vehicle according to claim 1 ,
wherein the exhaust apparatus comprises an exhaust pipe and an exhaust system member, and
the exhaust system member is located in the area on the vehicle-width-direction outer side of the frame member and on the front side of the pillar.

3. The side vehicle body structure of a vehicle according to claim 2 ,
wherein, below the frame member, the exhaust pipe is routed, the exhaust pipe connecting the internal combustion engine disposed on an inner side of the frame member in a vehicle width direction and the exhaust system member disposed on an outer side of the frame member in the vehicle width direction.

4. The side vehicle body structure of a vehicle according to claim 3 ,
wherein, in the vehicle body structure, a portion overlapping with the exhaust system member in a vehicle front view is located on a vehicle rear side relative to the exhaust system member.

5. The side vehicle body structure of a vehicle according to claim 4 ,
wherein the vehicle body structure comprises a front extending portion extending toward the vehicle front side up to at least immediately under the exhaust system member.

6. The side vehicle body structure of a vehicle according to claim 2 ,
wherein, in the vehicle body structure, a portion overlapping with the exhaust system member in a vehicle front view is located on a vehicle rear side relative to the exhaust system member.

7. The side vehicle body structure of a vehicle according to claim 6 ,
wherein the vehicle body structure comprises a front extending portion extending toward the vehicle front side up to at least immediately under the exhaust system member.

8. The side vehicle body structure of a vehicle according to claim 2 , wherein the exhaust system member comprises a gasoline particulate filter.

9. The side vehicle body structure of a vehicle according to claim 8 , wherein
the gasoline particulate filter comprises a body in which a filter is located and a connection portion having a width smaller than a width of the body; and
at least a portion of the body is disposed in a vehicle body lower portion on the vehicle front side relative to the pillar and on the vehicle-width-direction outer side relative to a tire stopper frame.
